Moriarty constructed a scenario that he was an innocent actor who Sherlock was obsessing on and framing.

The police and media bought it and Sherlock was hounded.
He then planned to kill himself and put the blame on Sherlock insisting Sherlock kill himself otherwise those close to him would be killed.
Sherlock saw no way out so committed suicide...although this was in fact faked by the use of a bungee rope and Darren Brown.
